The probability that at least 5 of them use their smartphones in meetings or classes will be 0.34.
<h3>What is probability?</h3>
Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
The number of combinations of 5 out of 10:

The Success factor is:
57% = 0.57
The failure factor is:
(100 - 57)%= 43%= 0.43
So the Probability will be :
0.57⁵ x 0.43⁵ x 252 ≈ 0.34

Answer:
Becuase if you supply and demand things there wont be enough needs and goods left
Explanation:
The probability that he can fit through the doorway without bending is 14.92%
<h3>How to find the p-value probability?</h3>
We are given;
Mean; μ = 69.5
Standard deviation; σ = 2.4
Sample mean; x' = 72
The standardized score is the value x decreased by the mean and then divided by the standard deviation. Thus;
z = (x' − μ)/σ
z = (72 − 69.5)/2.4
z = 1.04
Using p-value from z-score calculator gives us;
p-value = 0.1492 = 14.92%
Thus, the probability that he can fit through the doorway without bending is 14.92%
Complete Question is;
The Boeing 757-200 ER airliner carries 200 passengers and has doors with a height of 72 in. Heights of men are normally distributed with a mean of 69.5 in. and a standard deviation of 2.4 in. If a male passenger is randomly selected, find the probability that he can fit through the doorway without bending.

The net electric field is the vector sum of the components of the electric
field produced by the two charges.
The values of the magnitude and direction of the net electric field at the origin (approximate values) are;
- 12.6 ° above the negative x–axis
<h3>How are the net electric field magnitude and direction calculated?</h3>
The possible questions based on a similar question posted online are;
(a) The net electric field at the origin.
The electric field due to charge q₁ is given as follows;

Which gives;


Which gives;


Therefore;

The magnitude of the net electric field is therefore;
E =
≈ 131.6
- The magnitude of the net electric field at the origin is E ≈<u> 131.6 N/C</u>
(b) The direction of the net electric field at the origin.
